When this is the right choice
- Speed. 201°/s at the fingers — roughly three times the O6, which is what a fast pick cycle needs.
- Built to survive. Metal internal structure and a million-cycle test; a production cell hand, not a lab hand.
- 50 N grip at 607 g with a 28 kg load rating.
- Same SDK and ROS stack, so a cell that outgrows L6 can move to L20 without new software.
When it is the wrong choice
- Fine manipulation. Six active joints — in-hand rotation is not what this hand is for.
- Force or tactile sensing. Fingertip forces are rated, not measured; no tactile array.
- Lightweight arms. The 250 g over an O6 matters on a small cobot wrist.
Alternatives at a similar level
- Linker Hand O6 — 360 g, 50 kg grip, 74.8°/s — slower but lighter
- Linker Hand L20 Lite — 10+10 DOF, 800 g, 80 N grip, enveloping grasps
- Linker Hand O20 — 16 driven joints, 888 g, self-locking hold
- Linker Hand L30 Pro — 17+4 DOF tendon hand, 0.2 s open/close

Linker Hand L6 FAQ
How is the L6 different from the O6?
Same 6+5 DOF layout, different mechanism and intent. L6 uses a ball-screw electric cylinder for speed and duty cycle (201°/s, 1M cycles, 607 g); O6 is the lighter, cheaper linkage hand (360 g, 74.8°/s).
What does 1 million cycles mean for my cell?
A test result, not a warranty. At a 5 s cycle that is roughly 1,400 hours of continuous operation. Ask us for the wear-parts list and the replacement interval.
Can it run from 24 V DC directly?
Yes — DC 24 V ±10%, 0.2 A static and 5.6 A peak. Size the supply for the peak.
How long does it take to ship?
Confirmed per order at quotation.
